Electronic State of PuCoGa5 and NpCoGa5 as Probed by Polarized Neutrons
By using single crystals and polarized neutrons, we have measured the orbital and spin components of
the microscopic magnetization in the paramagnetic state of NpCoGa5 and PuCoGa5. The microscopic
magnetization of NpCoGa5 agrees with that observed in bulk susceptibility measurements and the
magnetic moment has spin and orbital contributions as expected for intermediate coupling. In contrast,
for PuCoGa5, which is a superconductor with a high transition temperature, the microscopic magnetization
in the paramagnetic state is small, temperature-independent, and significantly below the value
found with bulk techniques at low temperatures. The orbital moment dominates the magnetization.
